Grevis Gargantula Shield

The GGS, short for Grevis Gargantula Shield was an artificial layer replacing Utopia's Ozone layer. Its primary functions were to filter out the harmful UV rays and sustain human life. The GGS was developed by Paikan Corporation by an engineer called Grevis Hart.

The GGS layer consists of a formation of unstable atoms, taken from the rare metal Liberanium and bound together using UV light. The GGS is a thin film of light, barely visible to the naked eye. It needs to be sustained by projecting filtered UV light from multiple points on Utopia.These projections centers are called Gargantula Projectors and are maintained and owned by the Paikan Corporation.
